Side-On Fixed Liquid Crystalline Polymers: New Stationary Phases for High Performance Liquid Chromatography

New stationary phases are obtained by coating on a silica support liquid crystalline polysiloxanes with mesogenic side groups laterally attached to the polymer backbone through the flexible spacer. They show very good chromatographic performances in HPLC for the separation of polycyclic aromatic hyd...

Beschreibung
Zusammenfassung:	New stationary phases are obtained by coating on a silica support liquid crystalline polysiloxanes with mesogenic side groups laterally attached to the polymer backbone through the flexible spacer. They show very good chromatographic performances in HPLC for the separation of polycyclic aromatic hydrocarbons. Solute/mesogenic group interactions are evaluated through molecular mechanics calculations and correlated to the chromatographic results.
